Windows and Sunroof Not Working (Checked Fuse)

Recommended Posts

I have a 2003 996 TT in the US.


I have not done any modifications to the car and the windows and sunroof will not go down now all of a sudden.


  • I have checked all the fuses they are fine
  • The window still goes up and down a 1/2" or so when the door is opened and closed
  • The windows still work if I use the key in the keylock to open/close them.


I did a search and came back empty handed,


Any thoughts/ideas on what this could be?

Thanks for the feedback guys.


Yes the battery was changed recently but the windows and sunroof were working fine after they were changed. They just went bad all of a sudden today.


I tried pressing the button down for 10-15 seconds and nothing happened and then pressed them up for 10-15 seconds. Still nothing. 


Yes, the fuses I checked were indeed D1, D3, and B6.

Re-training involves holding the button for open until the window opens all the way and continue holding for an additional 10 seconds. Do the same for window down.

Each window and sunroof are trained separately.


If the window drops 1/2 inch when you activate the the door handle then you are getting power.
